Embodiment 1

[0034] refer to figure 1 , a portable bending tool, including a rod 1 and a bending assembly, the bending assembly includes a connector 2, a guide groove body 3 and a bayonet 4, one end of the connector is connected to the rod, and the other end is connected to the Described guide groove body, described guide groove body comprises a bottom surface 301 and first side 302 and second side 303 integrally connected with this bottom surface, constitutes the groove one 304 that limits the object to be held and bent, and described guide groove body is in the form of Arc-shaped, one end of the guide groove body is provided with the bayonet socket, so that the object to be bent passes through the bayonet socket and abuts against the edge of the bayonet socket.

[0035] In the present invention, the connecting head and one end of the rod are fixed by a screw 5 .

[0036] In the present invention, the rod part is preferably a cylindrical steel pipe. The bending assembly is preferably ma...

Embodiment 2

[0042] refer to image 3 , the portable bending tool described in this embodiment is an improvement on the basis of Embodiment 1, wherein:

[0043] A reinforcing rib 7 is provided between the guide groove body and the connecting head, one end of the reinforcing rib is connected to the second edge 402 of the bayonet socket, and the other end is connected to the upper part of the connecting head.

[0044] A reinforcing rib is provided to enhance the connection strength between the rod and the bending assembly, enhance the force application stability of the rod, share part of the force of the bending assembly, and improve the service life of the bending assembly.

[0045] The first side 701 of the rib is connected to the extension surface 305 of the first side 302 of the guide groove body.

[0046] The extension surface 305 cooperates with the reinforcing rib to further improve the connection strength between the rod and the bending assembly, and after the object to be bent is s...

Embodiment 3

[0048] refer to Figure 4 , the portable bending tool described in this embodiment is an improvement on the basis of Embodiment 2, wherein:

[0049] The rod portion is provided with a length scale line 8 .

[0050] During on-site construction, it is often necessary to use a ruler to measure, but the staff may forget to carry the ruler. At this time, they can use a portable bending tool to measure the size, record the size after measurement, and select the steel pipe for bending. For the bending operation of steel pipe members, if you want to get a very beautiful bending effect, you can pre-install sand in the steel pipe, seal the two ends of the steel pipe, and then insert the bending assembly to perform the bending bit by bit. Beautiful, there is no place to wrinkle at the bend.

[0051] The second side of the guide groove body is provided with arc scale lines 9 .

[0052] In this way, when performing the bending operation on site, it is convenient for the staff to compare...

Abstract

The invention provides a portable bending tool and a using method thereof, and belongs to the technical field of electric power tools. The portable bending tool comprises a rod part and a bending assembly, wherein the bending assembly comprises a connecting head, a guide groove body and a bayonet, one end of the connecting head is connected with the rod part, and the other end of the connecting head is connected with the guide groove body; and the guide groove body comprises a bottom surface and a first side surface as well as a second side surface which are integrally connected with the bottom surface, a first groove for limiting a to-be-bent object is formed by the bottom surface, the first side surface and the second side surface, the guide groove body is arc-shaped, the bayonet is formed in one end of the guide groove body, and the to-be-bent object is made to pass through the bayonet and abut against the edge of the bayonet. The portable bending tool is novel in structure, reasonable in design, ingenious in concept, suitable for bending operations of various pipes, steel bars, cable heads and the like, simple in operation process, high in flexibility, practical and convenient.

Description

technical field [0001] The invention belongs to the technical field of power tools, and relates to a portable bending tool and a using method thereof. Background technique [0002] At present, in the substation, some communication lines or secondary cables need to wear steel pipes when laying, so as to protect the communication optical cables or cables from damage. Ordinary bending tools are relatively heavy and need a power supply to drive them. They are all placed in the construction machine room. The staff carried out measurements on site and took the pipe to the machine room for bending. However, the angle after bending is still different from that on site. , doesn't look pretty enough. Sometimes for the convenience of drawing, take the pipe to find the bending place of the on-site equipment. The bending place is usually a channel steel or an angle steel. The bending is made by the edge of the channel steel or angle steel. If it goes in, it needs to be bent into other ...
